define a custom validator for the second date field (must be the second).
<h:inputDate id="lowerDate" value="#{yourBackinBean.lowerDate}"/>
<h:inputDate value="#{yourBackinBean.upperDate}"
validator="#{yourBackingBean.validateDates}"/>
public class YourBackingBean
{
public void validateDates(FacesContext context, UIComponent
component, Object value) throws ValidatorException
{
UIInput lowerComponent = (UIInput)component.findComponent("lowerDate");
if(lowerComponent.isValid())
{
Date lowerDate = lowerComponent.getValue();
Date upperDate = (Date)value;
// compare the two dates and throw a ValidatorException with
message if they are not valid
}
}
}
